Description

The Keith Black KB360.060 is a set of eight hypereutectic pistons designed for performance applications. These pistons feature a dome style with a 7cc volume and a bore size of 4.310 inches. They are constructed from a low-expansion 390 alloy with 16% silicon for tight piston-to-wall clearance.

Each piston includes fully machined head and valve reliefs, triple spiral lock rings, and CNC-machined pin bores. They also feature accumulator grooves for improved ring seal, machined-in oil returns, and diamond-finished skirts with mini grooves to reduce scuffing.
